Despite decades of considerable experimental effort, the scarcity of the experimental reaction rates for \(\gamma \)  process
makes it mandatory to rely heavily on
the Hauser-Feshbach (HF) statistical model [1]}, [2]} and the various nuclear ingredients in such a framework.
In reality, it remains a challenge to validate the reliability of the HF model and its inputs, and accordingly to put the \(\gamma \) -process calculations on a more reliable base.
Therefore, providing crucial new experimental cross sections relevant to \(\gamma \) -process will play a key role (see, e. g., [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}.)
Experimentally, most of the photodissociations in the \(\gamma \) -process nucleosynthesis studies have been so far derived from the reverse radiative capture
on the basis of the reciprocity theorem.
